Abstract
A method is disclosed for controlling a lighting fixture of a kind having individually colored light sources, e.g., LEDs, that emit light having a distinct luminous flux spectrum that varies in its initial spectral composition, that varies with temperature, and that degrades over time. The method controls such fixture so that it projects light having a predetermined desired flux spectrum despite variations in initial spectral characteristics, despite variations in temperature, and despite flux degradations over time.
